The owner's manual incorrectly states that the pistol can be shot either single-action or double-action. The pistol should NOT be shot double-action. Doing so may damage your gun.

The Hunting Master is a 6-shot revolver and has the highest power output of any commercially built precharged pneumatic air pistol. Manufactured with the utmost attention to quality and engineering. It meets the demands of diehard airgun hunters. Uses any type of .22 caliber airgun ammo without jamming. Overall length is 17.3", barrel length is 10" and weight is 3.05 lbs.

Things I liked:Very Hard hitting and incredibly accurate. I found the best pellet for it to be the Kodiak. Also works well with the Excite copper coated pointed pellets for better penetration. Every pellet hits the same hole at 25 yards. Easily goes through a 1 inch board. Buries pellets 2 inches into 4x4. Was not able to measure pellet speed with my Speeder 2000 Shooting Chrony. Chrony shows pellets to be moving at 3,800 FPS and I know they can't be traveling that fast. Chrony worked correctly with all other guns I have used it with. Think the problem with the speed measuring is that the gun blasts out a lot of air at very high velocity. I am sure the pellet is not traveling at the speed measured but air with other debris is traveling at supersonic speeds which is why the guns makes so much noise. The Chrony is probably measuring the supersonic speeds of the debris coming out the barrel. Later correctly measured initial velocity with Pro Chrono to be 844 fps with 21.12 grain copper coated Kodiak pellet. Things I would have changed:Does not have a pressure gage. Does not come with sights. Does not have a cover over the fill hole. Does not have a hammer block. Makes a lot of noise. Is picky about which pellets it will work with.What others should know:Others have said this gun works with any .22 pellet. I have not found that to be the case. Most of the pellets I have tried are a lose fit in the revolver magazine. When the gun is pointed down (which is the way I normally carry it for safety), the pellet directly behind the barrel falls into the barrel. When the hammer is pulled back the cylinder rotates and another pellets lines up with the barrel resulting in the first shot with a full revolver magazine firing two pellets at once. Use of the Kodiak and other pellets like them that are slightly bigger solves this problem as the pellets are a snug fit in the magazine and will not fall into the barrel.
This pistol does not have a hammer block. I accidently dropped the gun from 1 foot above a carpeted floor with the safety on. The gun discharged a pellet. The only safe way to carry it is to fire the first shot in a safe direction after loading a full magazine. That way if it falls it may discharge air but will not fire a pellet.

Things I liked:Everything except the trigger and no sights. I can get one-inch groups at 20 yards with 28.5 grain Eun-gins and about 645 fps initial muzzle velocity, dropping down to about 500 fps by 495 by the 6th shotThings I would have changed:Put some iron sights on it like the Hatsan and reduce the size of the butt on the hand grip - you don't need so much wood down there

Things I liked:The stock is very nice walnut and the barrel is well blued. The cylinder will take most any pellet. The action works like a single action revolver. It comes with two cylinders and a fill probe. Accuracy was very good with all the pellets I used. It can be shot offhand if needed when hunting.Things I would have changed:Evanix has made two changes that I don't like; they don't put their name on the gun and they don't come with a dust cover for the fill port. You should also know that there is no hammer block safety so if you bump the hammer while it is down the gun will shoot. The only safe way to carry the pistol is with the hammer cocked and the safety on because the safety doesn't block the hammer when its down.What others should know:It is advertised to shoot at 1000 fps but all I could get was 835 fps.

Theodore--The air reservoir is that large tube under the barrel. See the thumbnail images under the main image on the product's home page? Click on the 3rd or 4th image to enlarge it. The closed tube below the barrel is where you put the air. The gun doesn't have to be tethered to a tank or air source while shooting. You hook up to an air source only to fill the air reservoir. Then, you unhook from the air source and start shooting.

When shooting in double action it puts too much stress on the trigger, the hammer also does not go back as far as in single action so it has a large decrease in velocity that will vary per individual pistol.
